ROTARY MIXING-MILL.

SPECIFICATION forming part of Letters Patent No. 777,757, dated December 20, 1904.

Application filed January 13, 1900. Serial No. 1,308.

To all whom it may concern:

Be it known that we, ALBERT SIMON and AUeUsTE SIMON, citizens of the Republic of France, and residents of Cherbourg, France, have invented certain new and useful Improvements in Automatic Rotary Mixing-Mills, of which the following is a specification.

The object of our present invention is to provide a mixing apparatus for butter or similar materials and substances, said apparatus belonging to that class of kneading mills which have a rotary bed-plate and in which the mixing-runner does the work automatically without the assistance of the attendant.

The invention consists in the construction and peculiar arrangement of the mixing-runner'with relation to the bed-plate and in the construction and combination of other parts by means of which the desired end is attained.

In the accompanying drawings, Figure 1 is a front elevation of the apparatus. Fig. 2 is a partial longitudinal section. Fig. 3 is a plan View. Fig. 4 is a detail sectional view of the runner. Fig. 5 is a cross-sectional view of the runner. Fig. 6 shows a detail view of the stopping-rose in the outlet-passage. Fig. 7 is a bottom plan view of the same. Fig. 8 is a detail sectional view. Fig. 9 isa plan View of the corrugated table. Fig. 9 is an edge View of the table, partly broken away and in section. Fig. 10 is a detail sectional view of part of the table,'the pinion it, and means for adjusting the shaft of the roller. a plan view of part of the roller, the gearwheel t', means for rotating the roller, and the support for the latter. Fig. 11 is a detail end View of the parts a e 0 The improved apparatus is composed of the frame a, supporting the circular bed-plate or table 6, the hub Z) of which is revolubly mounted on the vertical hollow shaft 0. In the accompanying drawings ,we have shown a concave-shaped table provided with a central aperture communicating with the hollow shaft for the outlet of the liquid extracted in the operation. This form of construction is preferably adopted, though it will be understood that the invention may be equally applied to flat or slightly-convex-shaped tables and that the central outlet may be omitted and a cir- Fig. 10 is.

simple.

cular groove substituted therefor, said groove being provided on the periphery of the table, as seen in Fig. 8. Thetable is preferably made of cast-iron and provided with wooden mountings comprising staves 6 Figs. 3 and 4, but may be made of enameled cast-iron or other suitable material and provided with corrugations or radial grooves, as shown in Figs. 9 and 9. The main part is the mixing runner or roller cZ, mounted on a shaft d, journaled in the T-shaped bearing a, in the depending arm e of which moves a screw f, extending through a bearing 0 in the frame a and carrying a hand-wheel f. The end of the shaft (Z carries a crank (Z or any other power-transmission device.

The shaft carrying the roller (Z, Fig. 4, extends across the table-surface at an angle with the diameter thereof, which is very important in the improved construction. Indeed this arrangement permits of attaining the chief part of the proposed object, which is to make the work completely automatic, in that the butter or other material brought under the roller by the rotation of the table is completelypulverized and forced back in a direction that is different from the rotation of the table, as the shaft of the roller is not in coincidence with the radius of the table, so that the material is again brought under the roller in another position. Therefore the material is passed underthe roller at different velocities in accordance with its position on the table with respect to the axis of the latter. The mean angle of the roller-shaft relatively to the table is about eight degrees. This opening may, however, be'increased or diminished according as it is desired to turn the butter more or less completely. The wider the opening the more the butter will be lifted, and vice versa. It is simply by the movement of the roller that the butter can be turned during the operation.

The mechanism controlling the roller is very It consists of a loose screw C, fixed on the regulating fly wheel E, held in the socket D of the frame, in-whioh it turns freely, permitting the socket at T, which supports the roller (screw-threaded in its vertical part) to rise or fall, as desired. This socket at T supports the roller and its shaft. The operation is effected by turning the fly-wheel E from right to left, thus allowing the screwthreaded socket supporting the roller to ascend to the required heightthat is to say, at the necessary elevation above the table. To bring the roller nearer the table, all that is needed is to turn the fiy-wheel E from left to right, whereupon the screw-threaded socket supporting the roller and its shaft regulated by the screw 0 descends to the desired position. The screw-threaded socket, which also supports the roller, is provided with a guide F in one piece with it. The guide is held be: tween two ears of the socket D of the frame. In this manner the screw-threaded socket is held in one position and is prevented from turning when the operator turns the regulator E. The roller-shaft is thereby also kept in position at the desired angle to the table.

The characteristic feature of the roller con struction consists in the beveled end g, extending beyond the center of the table. Said extension may be of cylindrical shape when the table has a flat surface or is slightly con vex-shaped. The function of the extension g is to raise the layer of material when it is brought before the same, which is effected automatically by reason of the rotations in opposite directions of that portion of the roller and the table, said raising action permitting of the flow of whey or liquid extracted in the operation, and at the same time it breaks the layer and causes the same to change its position on the table. The said arrangement of the roller and the provision of its extension assists, therefore, in producing automatic action without any attendant.

The rotation of the roller obtained by means of the part (Z keyed on the shaft d is transmitted to the table by means of a pinion l2, provided with a threaded socket lb, screwed into the head of the roller (Z and keyed on the shaft (Z'. Said pinion ll, meshes with a gearwheel 2', formed on the periphery of the table. The roller (Z is controlled by means of the screw f, held in the support a and adapted to raise or lower the T-shaped bearing 6, supporting the shaft of the roller. Said bearing is guided in the part a, formed with two arms fitted over the extension 0" of the support 0 The roller is preferably made of solid wood, Fig. 3, or of hollow enameledcast-iron, Fig. 6. The usual symmetrically-arranged corrugations provided on the rollers are objectionable in various respects, and these objections are overcome by the arrangement shown in Fig. 9.

The liquid extracted during the operation flows off through the central opening in the table and through the hollow shaft 0 or through any other suitable openings or passages in accordance with the construction of the table. In order to prevent portions of the material from being carried away with said liquid, the outlet or outlets are provided with a stoppingrose 3', adapted to retain the portions of material.

The gearings and certain other parts of the apparatus are sheltered by casings k (shown in Figs. 1, 2, 3, and 4:) and arranged on suitable supports k.

In Fig. 8 we have shown the table as as being of slightly-convex shape and provided with a channel or slot (/0 extending around the table adjacent to the outer edge thereof for the outflow of liquid. The liquid falls upon chute x and thence falls onto a tray m Having fully described our invention, what we claim, and desire to secure by Letters Patent, is- 1 1. The mixing-mill comprising a frame, a revoluble table, radial grooves in the same, a mixing-runner having a length greater than the radius of the table and extending above and across said table, a shaft supporting the runner, said shaft being arranged at an angle relatively to the diameter of the table, as described, a pinion on the shaft of the runner, gear-teeth carried by the periphery of the table and with which teeth said pinion gears, and an opening for permitting the escape of liquid extracted in the operation, substantially as set fort 1.

2. The mixing-mill comprising a frame, a revoluble table, a mixing-runner extending across said table, a shaft supporting the runner, said shaft being arranged at an angle relatively to the diameter of the table as described, the said runner having a length greater than the radius of the table, means for actuating the runner and the table, a bearing for the shaft of the runner, a guide for said bearing, a screw working in a depending arm of said bearing and extending through a bearing on the frame, a hand-wheel on the screw, a central opening in the table, a hollow shaft in said opening supporting the revoluble table, and a stopping-rose in said opening, substantially as and for the purpose set forth.

In testimony whereof we have hereunto set our hands in presence of two witnesses.
